Density

Front

What is density?

Back

Density is the mass of an object divided by its volume. It is a measure of how much matter is packed into a given space.

Front

How do you calculate density?

Back

Density = Mass / Volume.

Front

What happens to an object that is denser than the liquid it is in?

Back

It sinks.

Front

What happens to an object that is less dense than the liquid it is in?

Back

It floats.

Front

Which liquid is typically the least dense?

Back

Oil is usually less dense than water and syrup.

Front

What is the relationship between density and buoyancy?

Back

An object will float in a liquid if it is less dense than the liquid; it will sink if it is more dense.

Front

What is the unit of density in the metric system?

Back

The unit of density is typically grams per cubic centimeter (g/cm³) or kilograms per cubic meter (kg/m³).

Front

If two objects have the same volume, but one has a greater mass, which one is denser?

Back

The object with the greater mass is denser.

Front

What is the density of water?

Back

The density of water is approximately 1 g/cm³ at 4°C.

Front

How does temperature affect the density of liquids?

Back

Generally, as temperature increases, the density of liquids decreases because they expand.
